A construction worker has fallen to his death at the site of a high-rise casino project on the Las Vegas Strip.
A Clark County fire spokesman says the man fell about 55 feet and was dead when crews arrived at the Project CityCenter site about 9 a.m.
He's the fourth worker to die working on the $7 billion casino-hotel project being built by casino giant MGM Mirage.
Nevada OSHA is investigating.
Officials say the man had a safety harness, but it's not clear yet if it was attached to anything.
Authorities say the man was an ironworker about 45 years old.
His name wasn't released.
